Folding Forum

Hi,
I started folding last week to help fight the Corona virus. Unfortunately, after updating to the new Nvidia driver (440.64), FAHControl shows that Cuda and OpenCL have not been detected, so the assigned GPU job won't start. I'm running Arch Linux (latest updates installed as of writing this).

At this point I'm not sure why cuInit() and clGetPlatformIDs() return errors. All the required packages are installed. It worked before updating the driver.

Thanks in advance for the help!

According to the Arch Linux Wiki I have to install these two packages. They should be the Arch equivalent of the Debian ones you mentioned.

Code: Select all

extra/ocl-icd 2.2.12-3 [installed] -> provides libOpenCL.so
    OpenCL ICD Bindings
extra/opencl-nvidia 440.64-2 [installed] -> matches version of the driver
    OpenCL implemention for NVIDIA

nvidia-smi is another nifty built-in util you can use to check out nvidia related info.

It is more than likely an issue with your nvidia drivers being out of whack after the upgrade process. I found out last week that stacking different nvidia drivers can kill it's functionality (FAH would work but I killed Steam!) You might be able to fix it by hopping into run level 3, removing all nvidia packages, install 440, and then reboot.

It should be something along these lines:

Hit CTRL+ALT+F1

Code: Select all

sudo telinit 3
sudo apt purge nvidia*
sudo apt update && sudo apt upgrade
bash ~/Desktop/NVIDIA-Linux-x86_64-440.46.run
sudo reboot

Be sure to check /var/lib/dkms/nvidia/440.46/build/make.log for any errors.

I had the same problem, on Manjaro. I guess you're using foldingathome-noroot; it was told me that cuda requires root, and I was suggested to install foldingathome (root client) instead. I've not found a way to allow foldingathome-noroot to detect cuda, but everything works with foldingathome (root).
